In the process for producing phenol, aldehyde, and ester, ketone production using and / or lignin and / or lignin sulfonic acid is heated to heat the raw material contained in lignin or lignin sulfonic acid to evaporate the desired material. During this process, the material is used to produce valuable materials through a heating effect on the solid internal components of the raw material. Production in this way requires good adherence to the external conditions for obtaining the desired material. This process, which produces valuable materials through its own firm ingredients, is rare but harmless. |
